The Rosetta conversion limits were measured on an M1 running macOS 15.3.1
and an M5 Max. A survey on an M5 running macOS 26.4 executes ANDN, RDRAND,
the rest of BMI1 and BMI2, LZCNT, PREFETCHW, CLFLUSHOPT, AVX, AVX2, FMA,
F16C and MOVBE while CPUID reports none of them, and raises an illegal
instruction for RDSEED, CLWB, RDPID, ADCX and ADOX.
Cult of the Lamb (PPSA06465, #2686) stops at start-up on the first one:
FAIL: unresolved ELF import pXJh3aVk8Ks from libSceContentDelete.prx
Both exports have been on main without an implementation (#2740); the
call itself has not been observed yet.
Orbital (cc408367, tools/ida/db_types.json:541-542) and SharpProspero
(5dfdb4b0, Interop/Content/ContentDelete.cs:25-42) agree on the
signatures: a 64-bit SceContentSearchContentId and a UTF-8 path. The
content library is empty on the host, since libSceContentExport exports
nothing into it, so no id or path can be found. SharpProspero gives only
NoPermission (0x809D5006) and no public source gives the not-found code,
so both calls throw with the id or path named once the null path and the
initialization are checked, like the "not in the host content library"
throws of #3724. sceContentDeleteById moves from
guest_content_unimplemented to the new guest_content_delete test.
NIDs pXJh3aVk8Ks and qC3QW+AltHs match tools/nid_names.py and the shadPS4
aerolib list.

On Linux, FIONREAD on a datagram socket reports the next datagram only,
where FreeBSD's sbavail counts every queued byte, so a read mark above 1
there could never fire. kevent now throws for it as before; stream
sockets and marks of 1 are unchanged.

The bundled PSNCore.prx of PPSA06888 calls sceNpTrophy2GetRewardIcon
with (context, handle, reward_id, buffer, size): once with a null buffer
to read the size, then with a buffer of that size. The function still
throws because the reward icon data is unknown.

kevent threw for NOTE_LOWAT. On a socket's EVFILT_READ it now sets the
low-water mark as FreeBSD 11's filt_soread does: the event fires once the
buffered bytes reach it, or at end of file or on a listening socket, and
a later change of the knote replaces it. EVFILT_WRITE takes a mark of 1,
where the host's writability stands in for a free byte; other write marks
and marks below 1 still throw. A pipe ignores the mark, as filt_piperead
does.

Metal Gear Solid 4 (PPSA18194) aborts on main when its launcher starts
the game: sceSystemServiceLoadExec runs the guest shutdown, a render
thread that then calls into the stopped AGC driver gets ProcessShutdown
back from LibcAwaitExit, and the exception unwinds into title code,
which terminates the process before the new executable starts.
LibcAwaitExit parks a thread only once an exit has been requested, and
LoadExec ran the shutdown without requesting one. It now starts the
shutdown the way exit does, so such threads wait until the process is
replaced.

A socket's EVFILT_WRITE and sceKernelAddWriteEvent reported the whole SO_SNDBUF in data, however much was already queued. FreeBSD 11.4's filt_sowrite reports sbspace, the space still free. On Linux the queued bytes from SIOCOUTQ are now taken off SO_SNDBUF. Windows has no query for the queued bytes and macOS is not wired up, so both keep reporting SO_SNDBUF; the debt entry says so.
fcntl threw for F_GETLK with an F_UNLCK request on the hosts that use POSIX locks, as Linux's F_GETLK rejects that type. FreeBSD 11.4's kern_fcntl accepts it and lf_getlock reports the first overlapping lock that lf_blocks lets conflict: another owner's lock, one of the two being a write lock. For an F_UNLCK request that is exactly another owner's write lock, the same set an F_RDLCK request finds, so the host is asked with F_RDLCK and the reply is written back as for the other types.
fopen_s returned ENOENT for every failed open, including an invalid mode, a directory opened for writing and the loop and long-name cases. C11 K.3.5.2.1 only asks for a nonzero value; Microsoft's CRT, which shares Dinkumware's library, returns errno. fopen_s now returns the errno fopen set.
PPSA28997 (IL2CPP) calls sceLibcBacktraceGetBufferSize and
sceLibcBacktraceSelf. On Linux the host call stack is captured with
backtrace and each frame is resolved to its module and offset with
dladdr, then written as a linked list of frame records. The record
layout is inferred and listed in TechnicalDebt. Windows throws.
